This HDB apartment is an excellent example of how subtle mix and match can be. What is interesting about the interior is that the designer opts for more modern flooring materials in the dining room, such as tiles, but still sticks to parquet in.
This is a nice-looking living room with smaller rug. Perhaps the key is to frame the rug with sofas / sofa and armchair combo / sofa and the window. And another trick is to fill up the room so the size doesn't look awkward.
